a) Extremity radiographs
- Should not be routinely performed prior to CT if a CT has been requested
- Depending on clinical acuity, these can be usually obtained safely after CT-imaging
b) CT angiogram (CTA) of extremities
- Indicated for a vascular extremity (e.g. pulseless foot)
- Can be obtained at time of initial CT
c) CT extremities for orthopedic injury
- Can be obtained after patient stabilized after treatment for initial CT findings
